Zohar and Marshall (2001) describe three aspects of intelligence. The first intelligence is the intellectual or rational intelligence (IQ), which would be the intelligence used "to solve logical or strategic problems". The second intelligence is emotional intelligence (EQ), a "basic requirement for the effective use of IQ". The third intelligence is spiritual intelligence (SQ), which is the "necessary foundation for the effective functioning of both IQ and EQ". Spiritual intelligence can be described as conscience.
